SPECIFICATION forming part of Letters Patent No. 559,016, dated April 28, 1896. Application filed July 20, 1892. gerial No 440,668. on model.)

To all whom it may concern:

Be it known that I,IIENRY A. WIsE W001), a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Improvement in Mechanical Movements, of which the following is a specification. i

The aim of this invention is to produce a new'and improved mechanical movement es pecially adapted for use as the bed-movement of printing-presses, and the same covers a modification or further carrying out of the invention -shown, described, and claimed in my application filed on the 11th day of July, 1892, Serial No. 439,677, Patent No. 481,128,

granted August 16, 1892.

- The invention consists of the device described and claimed inthis specification and Referring to the drawings and in detail, 11.

and 12 represent the usual side frames of a printing or other machine, and these side frames may be connected by the box-girder or tie-beam 13, and on the frames is mounted to reciprocate in the usual manner the reciprocating member or bed 14. Attached to the under side of the bed 14 is a rack 15 and a framing consisting of brackets 16 and 17 and the connecting piece or bar 18, to which piece 18 is secured or fastened the rack 19. The racks 15 and 19 are oppositely disposed or placed, as shown. The brackets 16 and 17 have extending ledges or projections 20 and 21, and fitting on these ledges is the frame or guide 23, which consists of aframe, as sh own, and two bearing-blocks 24 and 25, which fit on.the ledges 20 and 21, as shown, so that the frame 23 will be capable of a vertical rising and falling movement on said ledges 20 and 21. Also secured to said blocks 24 and 25 are brackets 240 and 250, in. which is jourbrackets 16 and 17. Thus as the frame 23 is raised or lowered the same will be kept square by means of this gearing, which constitutes a squaring mechanism.

p Pivotedon opposite sides of the guide or the. same and be caught thereby.

Attached to the framing or bed, as shown, are projections 37 and 38, against which levers 31 and 32 are adapted to strike, so that as theframe 23 reaches its lowest position the latch 35 will release the crank-block, and so that when the frame 23 reaches its highest position the'latch 36 will release the crankblock.

Thecrank-block 39 is swiveled by means of the extending shank 40 in a bracket 10, secured on the side of the driving-pinion 42, as shown, the crank-block being thereby substantially mounted in a crank-arm, which, as shown, is part of the gear 42. The crankblock fits into the guideway or framing 23, as shown, whereby as the crank-block revolves the frame 23 will be raised and lowered vertically, and whereby the frame 23 will keep nately engage the same, whereby the bed will.

be given its main or major reciprocation.

The gear 42 is secured on the shaft 43, which shaft 43 is journaled in an eccentric bushing 44, which has an extending arm 45,

to which is attached the yoke 46, and the yoke 46 has two rollers 47 and 48, which bear on opposite sides of cam 49. The cam 49,

as shown, has two surfaces 50 and 51, which are connected by easy inclines, whereby as the cam revolves, through the mechanism described, the gear 42 will be raised and lowered to properly and alternately engage the racks and 19.- The cam 49 is mounted on the shaft 52, which shaft 52 is mounted in bearings 53 and 54:, secured to the side frames 11 and 12.

The eccentric bushing before referred to is mounted in a bearing 56, formed in a bracket 57, which is bolted 011 the tie-beam 13, as shown, and also extending from the bearing 56 is a bearing 58. In this bearing 58 and in a bearing 59, secured to the side frame, is j ournaled the driving-shaft 60, on which may be mounted in the usual manner the usual loose and tight pulleys, by which, if desired, power may be transmitted to the mechanism.

Secured on the end of the shaft 60 is a pinion 63, which meshes with and drives the gear 42, and also secured on this shaft 60 is a pinion 64., which meshes with and drives gear 65, fast on the shaft 52.

Thus it will be seen that my invention con.- sists in the combination with a main driving mechanism of a peculiar reversing mechanism, and I wish here to state that any driving' mechanism may be used which will give the bed its major or main reciprocation.

The operation of my device is apparent and is as follows: The gear or pinion 42 engages with the rack 15 or 19, as the case may be, to give thebed its main reciprocation. As the gear revolves, the crank-block 39 will raise and lower the guide or frame 23. This will have no effect upon the horizontal reciprocation of the bed until the gear 12 becomes inoperative as the driver, when the block 39 will abut against. one of the bearings 24 or 25, as the case may be, and will gradually retard the bed to a state of rest, and then gradually start the same in the opposite direction, and deliver the bed back to the main driving mechanism at the proper speed. The latches will hold the block 39 positively against the blocks2=l and 25 during this action, and the block will be positively and absolutely released by the mechanism before described. The gear 42 is raised and lowered at the proper time by the cam mechanism before described. The stroke of the bed will be the length of rack 15 plus two pitch radii of gear 42, which is the radius at which the crankblock 39 is set, or the stroke of the bed will be the pitch circumference of gear 42 plus a pitch diameter.

I am aware that the details and arrangements of parts herein shown and described may be greatly varied by a skilled mechanic without departing from the scope of my invention as expressed in the claims.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is
